F. Storm Water Facility Planning. The intent of this provision is to comply with storm water management requirements, integrate storm water management/water quality systems into the site design as an amenity, and reduce the economic burden of storm water management systems on developments. Note: These guidelines address design issues and are not intended to diminish or alter other requirements in the City's storm water management regulations. 1. Integrate biofiltration swales, rain gardens, storm water planters, and other storm water management measures into the overall site design. Methods of filtration are listed below in order of preference: a. Incorporate the biofiltration system, including low-impact development(LID) features, as part of the landscape features of the development. If the biofiltration system is incorporated into the landscaping of the site's open space,then, upon approval of the City,the storm water facility may be counted as part of the required open space. Figure 318.070-8 The preferred method of handling storm water is through retention systems,such as rain gardens, incorporated as site amenities. Other low-impact development techniques are encouraged if i 1i. too -011 b. Locate biofiltration swales,ponds, or other approved biofiltration systems as part of a landscape screen. Trees may be planted near the grass swale as long as they do not substantially shade the grass or undermine soil structure within the swale. The swale or pond should be designed so it does not impede pedestrian circulation or shared parking between two or more properties. c. Where topography is favorable, locate the biofiltration swale, wet pond, or other approved biofiltration system within the paved parking or service area. The swale or pond should be landscaped as part of the required internal parking area landscaping and oriented so it does not impede pedestrian circulation. 36
